Raoult’s law states that the partial vapor pressione of each component in an ideal mixture of liquids is equal to the pressione di vapore of the pure component multiplied by its mole fraction in the liquid mixture. The governing formula is [latex]P_i = P_i^* x_i[/latex], where [latex]P_i[/latex] is the component’s partial pressure, [latex]P_i^*[/latex] is its pure vapor pressure, and [latex]x_i[/latex] is its mole fraction.
